The crested serpent eagle (Spilornis cheela hoya) has no distinct sexual dimorphic traits. In the current study, we report the results of an EE0.6 (EcoRI 0.6-kb fragment) sequence applied to S. cheela hoya and a novel random amplified polymorphic DNA (RAPD) marker that can be used to sex individuals within the species S. cheela hoya and Accipiter trivigatus formosae (crested goshawk). We used sex-specific primers for the avian CHD1 (chromo-helicase-DNA-binding 1) gene and the EE0.6 sequence in PCR assays to determine sex. In addition, 120 random primers were used for RAPD fingerprinting to search for novel sex-specific fragments of S. cheela hoya. The OPBB08 random primer generated a 1241-bp sex-specific fragment in all female S. cheela hoya. From the nucleotide sequence, PCR primers were designed to amplify 553-, 895-, and 194-bp sex-specific fragments present in all female S. cheela hoya. One of these primer pairs (ScBB08-7F/R) also amplified a male/female common fragment that can be used as an internal control (543bp). Moreover, one of the primer pairs (ScBB08-5aF/5bR) could be used to identify genders of A. trivigatus formosae. In conclusion, we identified novel sex-specific DNA markers of S. cheela hoya and A. trivigatus formosae that can be used for rapid and accurate sex identification.
